Smart Start review: Sanitation issues

This company is not helpful to customers. It's nearly impossible to get ahold of someone on the phone and the people who work at these garages are not smart start employees so they cannot help with issues either. Prices rise every few months without being informed. The device malfunctions regularly and the burden of the device malfunctioning falls on the customer and the customer is made to pay out of pocket for the device malfunctioning. During my last visit taking care of another malfunction of the device, I witnessed, and video recorded the device being plugged into the calibration machine by the mouthpiece, which is normal, but what is not normal is refusing to replace the mouthpiece before sending customers on their way. ALL customers have to put their mouth on their mouthpiece in order to use the device, and all of those mouth pieces are hooked up to the ONE machine with one plug for the mouthpiece, essentially having all customers swapping spit and germs, not to mention any form of mouth diseases. Pretty easy way to spread herpes and any other mouth STI/STD. I was told this is illegal and will be contacting a lawyer about the situation to see what steps to take next.
